Exhaust Ventilation FAQs

Nowadays, more and more people are looking into exhaust ventilation in order to find an effective solution to a wide variety of household needs. With the modern home design resulting in what is basically an airtight indoor space, there is more need than ever for exhaust ventilation.

What is the most important part of the ventilation system?

At the heart of all ventilation system is the exhaust ventilation fan. An ingeniously simple device that is finding favor in homes and workplaces around the world, an exhaust fan is simply a mechanical device that works by drawing out stale or otherwise unwanted air from an indoor space and courses it outwards through a system of vents and ducts. This system causes the unwanted air to be expelled to the exterior of a home or workspace where it cannot do harm to anyone. The result is much cleaner indoor air with a minimum of contaminants that can cause serious health issues.

What are the different types of ventilation fans?

Some of the most common types of exhaust fans are:

ceiling mounted exhaust fans
inline exhaust fans
wall mounted exhaust fans
combination exhaust fans
exterior remote mounted exhaust fans
kitchen range exhaust fans

These are only some of the more common types of exhaust fans that you can find in the typical home or workplace.

Why should you use the proper ventilation fan?

It is important to keep in mind that each of the ventilation fan designs is intended for a specific purpose, and while there may be some overlap between the different designs in terms of purpose and function, you will generally get the best results by choosing an exhaust ventilation system that is specifically intended for the location wherein you want to use the device.

What contaminants do exhaust ventilation systems protect against?

Among the most common contaminants found in the typical household and workplace are:

pesticides
gases
smoke
pet hair and debris
dust and dust mites
lead
asbestos
paint fumes
grease smells

All these and more are typically released in the indoor setting during the course of day to day activities, and a good exhaust ventilation system can help you deal with most of them in a safe and effective manner.

How can the airflow of the exhaust ventilation system be determined?

It can be difficult to determine the speed of the air entering an exhaust ventilation system via manual means. Instead, an airflow indicator is typically used in order to make it easy to determine whether or not there is enough air flowing through the system.

What type of airflow indicator should be used in a ventilation system?

There are many different types of airflow indicators designed for exhaust ventilation systems and their feasibility depends on the health risks involved. For low risk applications, a simple airflow indicator should be sufficient. For applications where there is a significant health risk however, it would be best to use a more sophisticated airflow indicator fitted with an alarm that goes off when there is insufficient airflow.
